Austrobaeckea pygmaea

Austrobaeckea pygmaea is a shrub, typically 10–50 cm (3.9–19.7 in) high and 60–100 cm (24–39 in) wide. Its leaves are narrowly egg-shaped with the narrower end towards the base, 3.5–8 mm (0.14–0.31 in) long, 0.5–1.1 mm (0.020–0.043 in) wide and 0.4–0.7 mm (0.016–0.028 in) thick on a petiole 0.2–0.4 mm (0.0079–0.0157 in) long. The flowers are 3–5 mm (0.12–0.20 in) in diameter and are borne in groups of up to three on peduncles 4–11 mm (0.16–0.43 in) long. The sepals are broadly triangular, 0.4–0.8 mm (0.016–0.031 in) long and the petals are white, 1.2–1.8 mm (0.047–0.071 in) long. There are 12 to 25 stamens, the ovary usually has two locules and the style is 0.7–0.8 mm (0.028–0.031 in) long. Flowering occurs from December to March and the fruit is a capsule 1.3–1.5 mm (0.051–0.059 in) long.

Austrobaeckea pygmaea is found on flats and winter-wet swamps, from near Lake Muir to near Albany in the Jarrah Forest and Warren biogeographic regions of south-western Western Australia.
